Engineering Contradiction Analysis
1Measurement precision
If conventional teaching methods are used, then measurement accuracy can be achieved, but operation complexity increases due to requiring specialized techniques for device operation, application software, and coordinate system settings
Solution Approach 1:
The patent creates a virtual copy of the measured object using three-dimensional sensor data. This virtual model allows operators to perform measurement teaching without needing specialized knowledge of the actual measuring device, coordinate systems, or application software. The virtual environment replicates the measurement geometry while eliminating the complexity of real device operation.
Solution Approach 2:
The patent introduces a measurement procedure information generation unit as an intermediary between the operator and the measuring device. This intermediary automatically generates measurement procedures based on simple object selection and measurement item specification, translating user-friendly inputs into complex measurement instructions without requiring the operator to understand the underlying complexity.
2Productivity
If offline teaching is used, then measurement efficiency improves, but specialized knowledge is still required for teaching simulation and part program generation
Solution Approach 1:
The system performs automatic measurement procedure generation without requiring operator intervention for complex programming tasks. The measurement procedure information generation unit automatically creates measurement procedures based on simple inputs (object selection and measurement item specification), making the system self-sufficient in generating complex measurement programs without specialized operator knowledge.
Solution Approach 2:
The patent uses three-dimensional sensor data to create a virtual replica of the measured object, which serves as the basis for automatic measurement procedure generation. This virtual copy enables offline teaching functionality while eliminating the need for operators to master teaching simulation software and part program generation techniques.
3Reliability
If online teaching is used, then measurement procedures can be generated with actual device operation, but measurement efficiency decreases due to device unavailability during teaching
Solution Approach 1:
The patent creates a virtual copy of the measured object using three-dimensional sensor data, enabling measurement procedure generation without using the actual measuring device. This virtual model preserves the geometric accuracy needed for reliable measurement procedures while allowing the physical device to remain available for production measurements.
Solution Approach 2:
The system performs measurement procedure generation in advance using three-dimensional sensor data and virtual modeling, before actual measurement takes place. This preliminary action creates ready-to-use measurement procedures that can be directly applied to the measuring device, eliminating the need for time-consuming online teaching and improving overall measurement efficiency.

AI summary
Provided are an offline teaching device and a measurement control device. The offline teaching device detects a shape of a measured object by a three-dimensional sensor unit, generates measurement procedure information in which measurement items are respectively associated with measurement points sequentially specified to the detected shape, and causes a measurement procedure information storage unit to store the measurement procedure information associated. The measurement control device detects a shape of a target measured object by a three-dimensional sensor unit, searches the measurement procedure information storage unit for a measured object having a shape substantially identical to a detected shape and specifies a measured object, extracts measurement procedure information on the specified measured object as measurement procedure information on the target measured object, and causes the use measuring device to measure the target measured object on the basis of the measurement procedure information extracted.
